The abundance and dark matter structure of
Strong dark matter interactions are proposed to alleviate the tension between observations and theoretical predictions in CDM. Among different interaction channels, self-interacting dark matter (SIDM) models have received considerable attention. However, most models and simulations have so far neglected the contribution of the baryons. First, I will present a combination of results from idealized SIDM simulations that explore the effect of a baryonic disk/bulge on the shape and density profile of dark matter halos. We find that the inclusion of baryons in the models help alleviate two of the long standing issues within CDM: i) the diversity ...
